In the Black Halls of the Outsider Gods

Woo had good writing buzz here from all the compliments I received...
I appreciate any feedback or discussion.
This project has legs now so here goes...

So my most recent thoughts on new content to design is explore ruins of the elder age. Ive done a few posts on my monster age of night and refered to it in my Exilon and Stnone Coast and Monster Island settings. Im a bit inspired by HPL's "The Mountains of Madness" and "The shadow out of time". Also there was a blog I used to read wich had a great vikings exploring a city of old ones in frozen north in a setting (if you remember who let me know). Brian Lumley also did vikings types exploring the corpse city of Cthulhu in one book and I used this as climax of my Viking Cthulhu game.

For this project I will touch on the monster empire in the age of night but will also look at the sealed cities of the outsiders who even the monster kings sealed away with black magic.

So my monster kings in the age of night was an age of mostly twilight and darkness ruled by abhumans serving evil gods. But even these evil gods were recognisable kin of other gods. Even demons and devils were part of the order established in the beginning of the universe. But there was before the first dawn intruder gods from the void who came into the world and hid in the dark placed under the earth and under the sea where light never reached. These beings were alien and while they might be called demons and evil gods in reality they are alien outsiders. Their insane mutterings and black magic gave aid to bad gods and demons and wizards that led to the end of the dawn age and began the age of night.

Early in this age the monster kings included worms and insect races. Bats and vultures came at the end of the age after the worms and bugs were betrayed and turned into food by their evil allies. But in the early times the dark beings from outside came from hiding and strided the world teaching blasphemous evil magic and devouring those who fled the monster kings. Some races hid in dungeons aided by the weakened good gods, many slept until the enemy were weakened. Most of the outsiders came from several cities and a few outposts. Sated by souls they rested and called more of their kind from the void.

Eventually their servants the monster kings and their gods realised their masters served only entopy and the world would be left but a husk so they turned on their evil mentors sealing them away and banishing them into the beyond. The monster kings wanted to rule forever but without their masters and new victims they turned on their allies. They destroyed the worm and insect emperors and propped up new warm blooded replacements. This was stable for a while but the dark races were lazy and greedy so they increasingly used modified humans and orcs as their legions. Finally these abhuman orc and humans revolted, then the sleeping and hidden peoples came from their great stone vaults and the old gods of creation returned ending the second age. Most of the monster races fled and hid to isolated places and beneath the earth.

Humans and orcs led by their modified kin became plentiful and came to dominate the world as the bred faster than the demihumans and beast folk of old. The ruined strongholds of the outsiders were hidden away in the cold of the north or the great lands of flame to the south or lesser outposts in hard to find places. But eventually humans found these places and some sought magic and power forgetting that the wickedest black magic of old was used to seal and conceal them.

The void is outside our universe but intertwined though ours. It is the vacuum the world was born into in the first act of the universes creation. It is a realm of anti life energy & entropy. It has magical shadow realms within its's curtain maze of darkness. Void beings guard the shadowmaze. It overlaps and interacts with many other planes such as the nightmare realms or parts of hell. Some witches walk through the void with magic or call on it's power. Evil star spirits in the sky and certain elder gods with their minions can bridge the worlds. All undead and level draining beings make use of its dank negative powers. Void beings change when they enter the world and human dreams to more recognisable horrors but made of hungry darkness 

The locations of these cities are in horrible places.
The evil gods and monster kings placed magical barriers to keep them hidden.
The entrances are usually sealed but there may be several
These hazards might be resisted by means of magic or research

The great chambers of the citadels are organic shaped like organs, bones, shells or exoskeletons. Perhaps these alien cities were once living and may again. Many chambers are unfathomable and the script of the outer ones is inscrutable. The chambers are huge for titanic outer horrors. The outer seals are in the script of the monster kings empire.

These were the krinoids* travelling worlds to study and experiment on life. In art they are showing the race of alchemists at study while shoggoths build this ruin. Sometimes it shows shoggoths as surly or resentful. Some scenes show naughty shoggoths being punished. Shoggoths are a mas of eyballs in a mass of thick ropy sticky protoplasm shat it shapes as it needs or forms into organs as they need.

d100 Great Chambers of the Outsiders Citadels
01 Mummified bodies of some strange alien servitor race, crowd the chamber, who's souls song ago drained as fuel for the hungry outer gods of the void
02 A great open sarcophagus with a elder titan's corps, it's sould long ago returned to the void
03 Lesser mortal servitors of the outer gods, mummified in hundreds of niches, which extracted their sould as food for the once livingcity of black magic
04 Thousands of carbonised human, beastfolk and demihuman corpses long ago consumed by the feeding outer ones
05 A great onyx sarcophagus with seals, wards and curses containing a slumbering demigod of the outer ones
06 A voidship of the outer ones designed to return to the outer realm of darkness, a rotting alien god sits at the controls slain by something long ago
07 A great pit sealed with a basalt plug with glyphs of warding and explosive runes, faint gibbering of some formless horror within can be heard
08 A great throne where some alien titan sat long ago
09 Hundreds of ashen silhouettes of worshippers, vaporised in a flash of soul devouring dark flame from a hungry god
10 A great brazier filled with charred skulls, if lit a black soul consuming flame rises from the pit
11 A great stone arch way with symbol of the outer ones, if a sacrifice is made at the nearby altar, the gate to another elder city is opened
12 Huge deformed headed statues line the chamber looking down at a altar, if a victim is sacrificed their eyes open and they will answer one question according to the inscrutable laws of the outer void
13 A great mirror disc surrounded by elder glyphs in a wall. If the right sequence of glyphs are pressed a gate to the negative realm of outer darkness outside the universe opens. All seeing this must save vs madness. If left open 1in4 chance per turn some being comes through
14 A great stone basin is before a squatting idol with jewelled eyes, inside is a bubbling tar like liquid, a formless spawn of the outer gods that will arise to attack thieves
15 A great diabolic face in the wall, by a altar with a grid of coloured gems. If aranged in correct sequence the mouth opens and is a gate to hell. Various sequences open in various locations in hell
16 Open pits in the floor and arcane symbols decorate the chamber. If explorers make any sound insane gibbering from amorphous horrors in the pits start up causing confusion to all who fail a save
17 Rows of huge sarcophagi against a wall, each with a lever. If pulled the sarcophagi opens and a umber hulk comes out, it will use it's glare while trying to awaken other sleepers here
18 A great chamber covered in outer god glyphs and other elder languages. If any are read a whispering mutter starts up and all in the chamber feel an alien presence from beyond viewing them. Any see invisible, detect magic or true sight may detect the scrying of alien beings from the void
19 A statue of a tentacled horror covered in mouths and eyes is central to the room with a altar. If a star shaped stone is removed from the altar before the statue, it begins to come to life unless the stone is returned
20 Signs of a adventurers camp from some time ago with lifeless husks with their throats torn out and looks of agonised horror on their faces
21 Rows of glass cylinders with various races in stasis within. A control altar can awaken them if operated correctly but if a mistake made they crumble into bones. The beings are from the age of darkness and they are slaves of the monster kings sent here as food
22 Hundreds of metal jars in niches fill the room holding ancient brains of mortal servants of the gods. If one is placed in niche on altar the jar glows and the prehistoric brain is able to speak though mostly they are long insane cultists
23 Great braziers surround a magic circle of elder runes. If lit and runes read the yellow smoke forms into a phantom robed being in tattered scalloped yellow robes and a mask. If addressed the being will remove its mask causing visitors to make a save or become confused. Those victims will dream of the yellow phantom and will be able to write but not comprehend a alien script
24 Thousands of tablets inscribed with language of the outer ones and the monster empire in niches mostly dealing with black magic and contacting the outer void
25 Strange metal tables with arm and leg restraints under crystalline apparatus. If a being is strapped down and the levers of the device are manipulated a mutagen ray pulses against the prisoner. A skilled operator can induce specific mutations otherwise they are random
26 A garden of gigantic alien fungus grows here. Many have magical effects or might be poisonous, but several are ambulant and hostile
27 A crystalline sphere in the middle with a door. If the control altar is activated while a being is inside images of the beings thoughts appear on the wall. A skillful operator sometimes gets future images that might come true
28 A series of crystal sarcophagi here with open lids, if anyone lays in one while a control altar is activated the person in the niche changes into a type of abhuman beast folk. A skilled operator can produce a specific type
29 A row of crystal chairs with a helmet and restraints. If a victim is in chair with helmet and the control altar is manipulated the seated makes a saving throw. On fail they are insane, success they can read and speak the outer gods alien language

31 much of the room is caved in with crushed alien servitors half buried under rubble
32 A altar with gems in niches in the centre of the chamber and several onyx sarcophagi. If the gems are taken beings take shape within coffins over a d3 rounds. The created servitors arise to attack
33 Ahuge ornamental bell, if struck all feel pain and sound continues for ten minutes, then a dimensional horror comes to see who has rung the bell. Normally the elder wizards know rituals of command and offer it blood
34 A circular clear crystal colum with a green glowing meteor inside. Their is a control altar if engaged correctly causes the meteor to glow and activated all the citadels lights. If performed wrong an alarm rings as the reaction goes critical. The stone glows too much spreading sickly rays that cause mutations and damage all in chamber. Then melts its way out of the column despite the inside flooding with blue gelatinous coolant, then melts through the floor
35 What looks like a huge alien creature is just a shed skin, if touched it crumbles to dust
36 A chamber covered in hundreds of huge eggs of some horrible being with a long hatching period, some are just broken shells
37 Dozens of man sized organic sacks hang from the ceiling
38 Chamber with hundreds of pots containing black liquid which twitches if approached, each is a baby formless spawn in hibernation

43 Two crystal sarcophogi, if a being lays in one and the control altar in between is manipulated a evil duplicate appears in the empty one
44 A huge metal mirror several stories high with a control altar before it. If altar manipulated the mirror shimmers opening a gate to a pocket universe where prisoners have been stored for aeons unaware of the passage of time
45 Salty pools with trilobites or squid or isopods or horseshoe crabs scuttling about
46 A stasis field with slave gladiators in mid battle used as a artwork, if field entered you are trapped till the end of time or freed by powerful magic (or ring of free action?). This is a artform of the elder gods and a control altar will usually be in a niche or hidden panel. Defective use of controls might leave victims turn to dust and bones
46 A courtyard with almost a hundred statues of slave peoples. A few are torturing the rest with cruel implements to dismembering and disembowel them. All look with horror at a podium in the centre with expressions of horror. All were petrified by the sight of a alien being from the void. Monsters used to stand on pedestal and enjoy the pain-garden view
46 A great circular chamber overgrown with thick carpet of mound, various monster mould types
48 Overgrown with a huge black tree in soil mass full of human like skeletons. The tree is plumbed into walls with stone pipes with a control altar for the climate controls.

62 Sacrificial pool where victims were drowned or dropped into a flooded pit to summon a water elemental
63 Crystal coffins where vampire agents sleep. One magic coffin turns a human like being into a vampire under a full moon if they make a saving throw. If they fail they just die and sose their soul
64 A hundred small apartments stacked up ten stories around inside of giant pit open to sky. Slaves lived here and their humble poor belongings and signs of a battle remain
65 A huge ceiling with hexagonal tubes in stone walls where sacrifices are fed to giant worms that grew into giant bugs for all kinds of purposes
66 A funerary temple in a great pit of ravenous worms. A walkway connects it to rest of the room floor. Inside a dozen cultist sons of kyusss await to be set on the world as revenge. Intruders awaken them but a lone quiet person might manipulate their control altar to awaken or destroy them
67 A great dark black pool full of eel swarms or venomous snakes, on a platform in the pool is a relic and a anti magic shell
68 The floor has hundreds of sarcophagi lids, if disturbed by outsiders or without prayers to them awakens mummies of the builder alien race

78 Dozens of control altars studded with gem controls, crystal screens on walls show views outside the city if controls operated properly. With time they might unlock a few interior viewing crystals
79 Pit full of beast headed mummies a dumped here long ago. Some have bejewelled decorations. If pit entered some mummies awaken to kill intruders
80 Room with control altars with slots for cystals in them. The wall have other colourd crystals if inserted a crystal screen lowers from ceiling and
81 Area seems to have high pressure, save or noseblled and sore ears. if a turn is spent in here say examining outsider silver runes in the stone, spirits from beyond began to manifest forms starting with things resembling deep sea fish made of darkness. one a roundfor a turn 1 HD, the next turn a void demon per round appears

89 Chamber walls are flesh with veins and tuxtured skin, pulsing organs are visible through skin. Slime filled pits grow various monsters and servitor races. Placing a sample specimen creature in pool and letting it digest lets you grow a servitor copy obedient to the outer ones. Operating a living console altar can grow other beings if you know how but most are hostile
90 Huge room with piles of treasure and chests actually all cult mimics 
91 A museum with plinths each occupied one has a spotlight from above on it. The occupied plinths have various strange relics many cursed and most unfathomable. Many perform magic at some cost like HP or attribute points or levels

100 A huge broken apparatus here for some great magical effect requiring burning gems and sacrificing humans, its vessels are shattered, its scaffolding burned

One option is when inside there are a d6 doors. Every time you enter a door you go to a random chamber and and door after a turn goes to a different room. Possible some rooms are trap rooms with a single one way door inside. Obviously maps are useless.

Will be more of this stuff...
